Organic light emitting diode module with optical signal transmission

Abstract

An organic light emitting diode (OLED) module with optical signal transmission includes a substrate, an OLED element, an optical signal transmission element and a spacing member. The substrate includes a light emitting region, an optical transmission region, and a spacing region spaced between the light emitting region and an optical transmission region. The OLED element is disposed in the light emitting region, and includes a first electrode layer, a second electrode layer and an organic light emitting layer. The optical signal transmission element is disposed in the optical transmission region and transmits an optical signal to the exterior. The spacing member is disposed in the spacing region, and includes a lower portion and an upper portion having a width greater than that of the lower portion. Thus, the present invention provides a simplified manufacturing process, a reduced overall volume and lowered production costs.
